Why Are People With Diabetes More Prone To UTI?
Category : Diabetes And Urinary Tract Infections
There are likely several reasons.
First, people with diabetes may have poor circulation, which reduces the ability of white blood cells to travel in the body and fight off any kind of infection.
Diabetes impairs some parts of your immune response. You have fewer white blood cells and T cells to fight off invading bacteria, viruses, and fungi. For the same reason, diabetics often develop UTIs caused by less commonly encountered germs. Routine antibiotics may be ineffective.
Second, high blood glucose levels can also raise the risk of a UTI.
High blood sugars can be a result of both Type 1 and Type 2 diabetes.
The pancreas produces a hormone called insulin, which helps to transport glucose from the bloodstream into tissue cells to be utilized as energy.
In type 1 diabetes, the pancreas is unable to produce sufficient amounts of insulin.
In contrast, type 2 diabetes is a result of an impaired response to insulin by cells.
Excess glucose is filtered in the kidneys and results in significantly higher urine glucose concentrations when compared to the urine of non-diabetics.
Filtered glucose attracts water into the renal tubules, which can increase the urge and frequency of urination.
High glucose concentrations in the urine provide an abundant source of nutrients for bacteria, which can proliferate and cause an infection.
And third, some people with diabetes have bladders that don’t empty as well as they should. As a result, urine stays in the bladder too long and becomes a breeding ground for bacteria.
Nerve damage can keep your bladder from emptying, either by weakening muscles or scrambling the signals between your brain and urinary system.
Urine that remains in your body too long poses a greater infection risk.
